I’ve been trying to spawn Corydoras guapore for quite some time. I was given 4 fish from John Reid around 18 months ago and they’ve grown on to be two pairs. C. guapore are an unusual corydoras and successful breeding records are few.
The fish have been rather active recently and their colour has become more intense. I’ve been watching them closely for spawning signs but was on holiday last week and busy with work in the garden. It wasn’t until I did a water change last Sunday that I noticed there were some fungused eggs in the tank.
As is often the case with corydoras however it seems that they will spawn more than once over a period of time. I was lucky enough to capture some spawning activity in this (rather poor quality) video.
Fingers crossed for some fry although the eggs are few and very small.
